Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority under 35 U.S.C. .sctn.119
from German Patent Application No. 10 2014 212 990.7, filed Jul. 4,
2014, the entire disclosure of which is herein expressly
incorporated by reference.
BACKGROUND AND SUMMARY OF THE INVENTION
[0002] The invention relates to methods and devices for
establishing a voice connection between the driver of a
single-track vehicle and an emergency call center.
[0003] Emergency call systems for motor vehicles, which, in the
case of an accident involving the motor vehicle, for example,
automatically make an emergency call to an emergency call center,
are known. For example, an emergency call device for a motorcycle
is known from DE 10 2008 023 243 A1 in which, by means of sensors
and a control unit, the sensor data are analyzed and evaluated and
a decision is made automatically as to whether an accident
involving the motorcycle has occurred. Optionally, an emergency
call is sent to a center by means of a communication unit. The
emergency call can also contain positional data of the motorcycle
which are determined using a navigation device working on the basis
of the GPS satellite system provided in the navigation device. To
make the decision as to whether an accident involving the
motorcycle has occurred, speed sensors, acceleration sensors, tilt
sensors, temperature sensors, contact sensors or pressure sensors
are provided on the steering wheel and on the seating surface
and/or on the footrests of the motorcycle. It is particularly
possible to detect if the driver is thrown from the motorcycle
during an accident.
[0004] DE 10 2008 023 243 A1 also provides the possibility of voice
data being transmitted to the emergency call center with the
emergency call. Moreover, the possibility is provided for the
emergency call center to call the emergency call device back. The
emergency call device is designed such that it can be called back
and accept this callback.
[0005] It is the object of the invention to enable a connection to
be established in as reliable a manner as possible between an
emergency call center and a driver of a single-track vehicle who
has been in an accident if the driver has been thrown from the
vehicle as a result of the accident.
[0006] This and other objects are achieved according to the
invention by a method for establishing a voice connection between
the driver of a single-track vehicle and an emergency call center,
wherein, on the one hand, a telematics unit provided on the vehicle
transmits emergency call signals to the emergency call center and,
on the other hand, the voice connection between the driver and the
emergency call center is established by way of the telematics unit
and a mobile radio device carried by the driver of the vehicle.
[0007] The invention is based on the insight that drivers of
single-tracked vehicles are generally carrying mobile radio devices
with them these days, particularly a cellular phone. With the
invention, it is made possible for an emergency call center to
establish contact with the driver via this mobile radio device
after it has received an emergency call generated automatically by
the telematics unit. Through this connection between the emergency
call center and the driver--which, incidentally, is independent of
the telematics unit and hence independent of the vehicle--it can
advantageously be achieved that it is also possible for the
emergency call center to speak with the driver even if he were
thrown from the vehicle or has left the vehicle for another reason,
or if there are loud environmental noises there.
[0008] In this context, single-track vehicles are particularly
regarded as being motorized vehicles such as motorcycles, motor
scooters, mopeds, motor-assisted bicycles and electric bicycles.
However, the invention can also be used in conjunction with
non-motorized single-track vehicles such as bicycles, for
example.
[0009] Some examples of mobile radio devices that can be used are
cellular phones, which are able to establish communication links on
the basis of a mobile radio standard such as, for example, the
Global System for Mobile Communications (GSM) standard,
particularly including higher versions such as GSM2, GSM3 and/or
GSM4 (LTE). In relation to the invention, other radio-based,
wireless technologies can also be used as a communication link,
such as Wireless Local Area Network technologies (WLAN, Wi-Fi)
according to the group of IEEE 802.11x standards, Bluetooth (IEEE
802.15.1) or Near Field Communication (NFC). The invention can
particularly also be used when a communication link between a
transmitter and a receiver is built over several legs on the basis
of several radio technologies, for example for a headset of the
driver that can communicate via Wi-Fi with the telematics unit of
the vehicle and from the telematics unit to the emergency call
center via a GSM mobile radio link.
[0010] According to an advantageous exemplary embodiment of the
invention, accident-specific data are transmitted from the
telematics unit to the emergency call center by way of the
emergency call signals if the vehicle is involved in an accident.
The transmission can particularly be triggered automatically by the
telematics unit. Accident-specific data of the vehicle can be, for
example, positional data, speed data, acceleration data, tilt angle
data or data from special accident sensors of the vehicle, such as
deformation data detected on the vehicle frame, for example.
[0011] In a preferred exemplary embodiment of the invention, the
emergency call signals are transmitted via a first communication
channel and the voice connection is established via a second
communication channel that is separate and, in particular,
independent from the first communication link.
[0012] With the invention, it can particularly and advantageously
be achieved that only predetermined data of the telematics unit,
particularly data of the vehicle sensors and/or data stored in the
vehicle, are transmitted via a first communication channel to the
emergency call center and, on a second communication channel, only
the voice connection between the driver and the emergency call
center occurs. The first communication channel can particularly
only exist between the telematics unit and emergency call center
and the second communication channel, independently of the first
communication channel, between a mobile radio device carried along
by the driver, e.g., from a cellular phone of the driver, and the
emergency call center. Particularly through the separate
transmission of data, particularly of data generated automatically
in the vehicle, and of voice signals, particularly of voice signals
of the driver, via two separate technical communication channels,
it can also be achieved, for example, that reliable sensor signals
are transmitted with priority. Moreover, secure and, optionally,
redundant data transmission can occur if an at least partially
independent infrastructure, for example a distinct mobile radio
unit with a distinct SIM card, is used for each of the two
channels. In this way, the communication links can optionally also
be established reliably and efficiently in the case of
country-specific differences or special features, such as when
different mobile radio standards are used.
[0013] In an especially advantageous exemplary embodiment of the
invention, identification data of the mobile radio device are
stored in the telematics unit. These identification data can then
be forwarded automatically to the emergency call center by the
telematics unit and particularly by way of the emergency call
signals. Particularly if the identification data are transmitted
with the first emergency call signals to the emergency call center,
the emergency call center can be enabled very quickly upon receipt
of the automatic emergency call to establish a direct connection to
the mobile radio device of the driver via the corresponding
identification data. The identification data particularly
constitute link data for a radio network such as, for example, the
mobile phone number of a cellular phone, an IP address for a mobile
radio device registered on a wireless computer network such as
Wi-Fi, a corresponding Bluetooth address, or the like.
[0014] With the invention a provision can particularly
advantageously be made that a cellular phone being carried by the
driver is, on the one hand, used in a manner that is technically
independent of a telematics unit or emergency call system
integrated firmly in the vehicle and, on the other hand,
functionally integrated into the further processing of an emergency
call made by the telematics unit, for example through a callback to
the mobile telephone made from the emergency call center. For this
purpose, all that is required of the telematics unit is that the
corresponding identification or mobile phone number be stored
therein and that this number be transmitted with the emergency call
to the emergency call center.
[0015] In another advantageous exemplary embodiment of the
invention, several identification numbers for a mobile radio device
or several identification numbers for different respective mobile
radio devices are stored in the vehicle, particularly in the
telematics unit. For a dual SIM cellular phone, for example, the
two numbers of the two SIM cards can be stored. It is also possible
for the identification data for different mobile radio devices of
different drivers to be stored, respectively. During the
transmission of the identification data to the emergency call
center, it is then possible for all or selected identification data
to be transmitted as appropriate in order to enable reliable
establishment of a connection to the driver.
[0016] To enable appropriate selection from a plurality of
identification data stored in or in association with the vehicle, a
provision can advantageously be made that time data be allocated
and stored for the multiple sets of identification data which are
representative of when the mobile radio devices associated with the
respective identification data were used in conjunction with the
vehicle and/or were stored in the memory. This makes it possible to
evaluate the respective currentness of the identification data
and/or the frequency of use of the respective mobile radio device
in conjunction with the vehicle. In this way, it can particularly
be decided with respect to the transmission of the emergency call
signals which of the identification data are to be transmitted to
the emergency call center. Moreover, on the basis of the number
allocations, an appropriate sequence can be established in the
attempts at establishing a connection between emergency call
centers in order to actually reach the driver currently involved in
an accident as quickly as possible.
[0017] In another advantageous exemplary embodiment of the
invention, the mobile radio device is provided in a piece of
protective equipment of the driver. It can particularly be
integrated therein, for example in a helmet or a combination
protective suit.
[0018] To establish the voice connection, the telematics unit can
also be used as a switching center between a mobile speech device
of the driver and emergency call centers. The speech device can,
for example, be a cellular phone, a radio device or a completely or
partially wired voice system between driver, co-driver and/or a
control device of the vehicle.
[0019] The establishment of the voice connection can particularly
be initiated by the telematics unit, by the emergency call center,
by the mobile radio device and/or by the driver.
[0020] With the invention, an emergency call system for a
single-track vehicle can also be specified in order to establish a
voice connection between the driver of the single-track vehicle and
an emergency call center. It comprises a telematics unit and a
mobile radio device carried by the driver. The emergency call
system is set up such that it can transmit emergency call signals
to the emergency call center by way of the telematics unit and that
the voice connection between the driver and the emergency call
center can be established by way of the telematics unit and the
mobile radio device.
[0021] A commensurate telematics unit for establishing a voice
connection between a driver and an emergency call center is set up
such that the telematics unit can transmit emergency call signals
to the emergency call center and that the voice connection between
the driver and the emergency call center can be established by way
of the telematics unit and the mobile radio device. With the
invention, a single-track vehicle can also be specified which
comprises such a telematics unit.
[0022] In the framework of the invention, features from the
publication DE 10 2008 023 243 A1 cited herein can also be provided
for the emergency call system and operation thereof. This
publication is hereby incorporated into the present description by
reference for this purpose.
[0023] Other objects, advantages and novel features of the present
invention will become apparent from the following detailed
description of one or more preferred embodiments when considered in
conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0024] FIG. 1 is a schematic block diagram of a first emergency
call system;
[0025] FIG. 2 is a schematic block diagram of a second emergency
call system; and
[0026] FIG. 3 is a schematic block diagram of a third emergency
call system.
DETAILED DESCRIPTION OF THE DRAWINGS
[0027] In the figures, the same or similar parts or functions are
designated by the same reference symbols across the figures. As
will also readily be understood, parts and functions shown in one
figure can also be used in exemplary embodiments in other figures
even if they are not depicted therein.
[0028] In the emergency call system 1 shown in FIG. 1 for a
motorcycle 2, a telematics unit 5 is provided in an
intrusion-protected area 20 of the motorcycle 2 with which mobile
radio communication with an emergency call center 4 can occur via a
communication channel 7. For this purpose, the telematics unit 5
has inherently known mobile radio components such as, for example,
a SIM card, an antenna, etc. The connection to the emergency call
center 4 is established via a mobile radio network infrastructure
having appropriate interfaces. The communication channel 7 can have
at least partially wired connection parts, computer network-bound
and, particularly, internet-based connection parts. The emergency
call center 4 particularly includes a computer and a voice
interface such as a telephone or a headset, for example. The
emergency call center 4 can also include a distributed computer
network. It can be operated by a company, for example the
manufacturer of the telematics unit and/or the manufacturer of the
motorcycle. The emergency call center can also be part of a public
institution, for example a rescue control center of a fire
department or of other emergency rescue services.
[0029] Various sensors are provided on the motorcycle 2 which
detect, for example, driving dynamic variables and/or
accident-specific variables, for example a speed sensor 21 and an
acceleration sensor 22. Their sensor values can be transmitted via
a data bus 24 to the telematics unit 5. A GPS positional sensor 23
is provided in the intrusion-protected area 20 of the motorcycle 2
to whose geographic positional data the telematics unit 5 has
access. Additional sensors, such as a tilt sensor, for example, can
be provided in the intrusion-protected area 20.
[0030] FIG. 1 also shows a cellular phone 3 that the driver of the
motorcycle 2 carries with him, for example in the pocket of his
protective suit. The mobile phone number associated with this
mobile telephone 3 is stored in the electronic data storage 6 of
the telematics unit 5. The cellular phone 3 has appropriate
components for a mobile radio link, for example based on the
standards GSM, GSM2, GSM3 and/or GSM4 (LTE). It can also have other
radio interfaces, such as a Wi-Fi interface, a Bluetooth interface
or an NFC interface. A wired interface, such as a USB interface,
for example, can also be provided. The cellular phone 3 can have a
plurality of other functions, particularly functions controlled by
use of computer programs (including apps), and particularly be a
so-called smart phone. The inputting and saving of the mobile phone
number in the data storage 6 of the telematics unit 5 can be done
manually by the driver, or these processes can be performed
automatically in whole or in part, particularly under the control
of the telematics unit 5 and, for example, by way of a suitable
application (so-called "app") stored on the cellular phone 3 and
using one of the respective existing wireless or wired interfaces
such as Bluetooth, Wi-Fi, USB, etc.
[0031] If it is detected on the basis of registered sensor data of
the motorcycle 2, for example by an evaluation and control unit
(not shown here) of the motorcycle 2, that the motorcycle 2 has
been involved in an accident, then the telematics unit 5 builds the
communication link 7 to the emergency call center 4 and transmits
to it by way of corresponding emergency call signals an accident
report and, optionally, data registered by the sensors 21, 22,
etc., of the motorcycle 2. The current positional data of the
motorcycle 2 detected by the sensor 23 are also transmitted to the
emergency call center 4 on the basis of which the emergency call
center 4 can have rescue workers directed to the scene of the
accident. The telematics unit 5 also transmits the mobile phone
number of the cellular phone 3 stored in the data storage 6 via the
communication link 7 to the emergency call center 4. Using this
mobile phone number, the emergency call center 4 can establish a
communication link 8 to the cellular phone 3, i.e., directly to the
driver involved in an accident, that is independent from the
communication link 7. As a result, a voice and/or data connection
can be established between the cellular phone 3 and the emergency
call center 4 independently of whether the driver involved in an
accident is located at the motorcycle 2 or at a distance therefrom.
A person at the emergency call center 4 can make inquiries
telephonically, for example, via the communication link 8. In
addition, it is also possible to transmit data, for example text
messages, images and/or video sequences produced with the cellular
phone 3, via this communication link 8 to the emergency call center
4. The communication link 8 can particularly be established by the
cellular phone 3 via one of the GSM mobile radio standards.
[0032] FIG. 2 shows an emergency call system 1a in which the
telematics unit 10 also has an interface 9 with which a data
connection and/or voice connection can be established via a
communication path 11 to a mobile hands-free speech device 3a
carried along by the driver in his helmet. The hands-free speech
device 3a has an appropriate interface (not shown in the figure)
for this purpose. The interface 9 enables at least partially
wireless data transfer and can be embodied, for example, as a Wi-Fi
or Bluetooth interface. Via the interface 9, an identification
number such as, for example, an IP address of the hands-free speech
device 3a can be read into or assigned automatically in whole or in
part to the telematics unit 10 and stored in the data storage 6. If
an emergency call is made in the motorcycle 2 by the telematics
unit 10, appropriate accident-related sensor data, positional data,
etc., are transmitted to the emergency call center 4 via the
communication channel 7. Furthermore, the telematics unit 10
creates a data- and/or voice connection to the hands-free speech
device 3a of the driver via the interface 9 and the communication
path 11 and automatically establishes a commensurate connection
between the hands-free speech device 3a and the emergency call
center 4. As a result, the emergency call center can contact the
driver directly telephonically and/or by data transfer.
Particularly if the communication path is wireless, such contact
can be ensured even if the driver is not on or at the motorcycle,
for example because he was thrown from the motorcycle during the
accident.
[0033] In the emergency call system 1b shown in FIG. 3, the
telematics unit 10 of the motorcycle 2 transmits emergency call
signals to the emergency call center 4 via the communication
channel 7 after the accident. In addition, a telephone number of
the emergency call center 4 is stored in its data storage 6 and a
mobile telephone number of the mobile telephone 3. In a first
exemplary embodiment, the mobile telephone number of the mobile
telephone 3 is transmitted with the emergency call to the emergency
call center 4, which then calls the mobile telephone 3 via the
communication channel 8 in order to speak with the driver at the
scene of the accident. In a second exemplary embodiment, the
telematics unit 10 transmits the emergency call number of the
emergency call center 4 from the data storage 6 via the interface 9
(e.g., Wi-Fi) and communication path 11 to the cellular phone 3.
The emergency call center 4 can then be called at this number via
the communication channel 8 using the mobile telephone 3 by the
driver himself or automatically by a program (app) stored in the
cellular phone 3 and/or in a manner mediated by the telematics unit
10. In a third exemplary embodiment, the telematics unit 10
transmits the mobile phone number of the cellular phone 3 to the
emergency call center 4 via the communication channel 7 and the
emergency call number of the emergency call center to the mobile
telephone 3 via the communication channel 8. Both the emergency
call center 4 and the mobile telephone 3 thus have the contact data
of the other, thus redundantly ensuring that a connection can be
established between the emergency call center 4 and the driver via
the communication channel 8. The transmission of the identification
number of the cellular phone 3 and/or of the emergency call number
between the mobile telephone 3 and the memory 6 can occur via the
interface 9, which can be wired, e.g., as a USB interface, or
wireless, e.g., as a Wi-Fi or Bluetooth interface, for this
purpose.
[0034] The device and system components described are particularly
controlled using computer programs and can also have inherently
known elements of computers and digital control devices such as a
microprocessor, volatile and non-volatile memory, interfaces, etc.
The invention can therefore also be implemented in whole or in part
in the form of a computer program product which brings about the
inventive process in whole or in part upon being loaded and
executed on a computer. For example, it can be made available in
the form of a data carrier such as a CD/DVD or a USB stick or even
in the form of one or more files on a server from which the
computer program can be downloaded.
[0035] The foregoing disclosure has been set forth merely to
illustrate the invention and is not intended to be limiting. Since
modifications of the disclosed embodiments incorporating the spirit
and substance of the invention may occur to persons skilled in the
art, the invention should be construed to include everything within
the scope of the appended claims and equivalents thereof.
